WebNov 19, 2010 · How many atomic shells does sodium atom contain? It has 11 eletron and 3 outer shells. The rows going across the periodic table is known as periods and contain elements with the same number of? WebSep 5, 2024 · This means that the first shell and second shells of Na atom are filled to the maximum number of electrons. The first shell (1s) is filled with 2 electrons. The second shell (2s and 2p) has a total of 8 electrons. And, the third (last) shell has 1 electron. The shell diagram of the Na atom is shown below. The shell nearest the nucleus (first ...

In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on farther and farther from the nucleus. The shells correspond to the principal quantum numbers (n = 1, 2, 3, 4 ...) or are labeled alphabetically with the letters used in X-ray notation (K, L, M, ...).

WebIn the progression thus far, three atoms—hydrogen, lithium, and sodium—have one electron in the outermost shell. As stated above, it is these outermost electrons that determine the chemical properties of an atom. Therefore, these three elements should have similar properties, as indeed they do. WebJan 20, 2013 · A Sodium atom has three shells. For future reference, this can be discovered later by looking at which period an element falls in. For example, all group 1 elements have 1 shell, all... WebThe first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons.
